Over the next two decades, the U.S. electric grid will face unprecedented technological challenges stemming from the growth of distributed and intermittent new energy sources such as solar and wind power, ...

A new type of active metamaterial that incorporates semiconductor devices into conventional metamaterial structures is demonstrating an ability to have power gain while retaining its negative refraction property, a first ...

(PhysOrg.com) -- By demonstrating that an artificial atom embedded in a transmission line can route a single photon from an input port to one of two output ports, physicists have built the first router working ...

A joint cooperation between three research groups at nanoGUNE reports an innovative method to focus infrared light with tapered transmission lines to nanometer-size dimensions. This device could trigger the ...

Nokia Siemens Networks has successfully tested a technology that could drastically increase the data carrying capacity of standard copper wires. The company achieved data transmission speeds of 825 megabits per second (Mbps) ...

Panasonic today announced the development of a new terahertz (THz) detector using a Gallium Nitride (GaN) transistor. The detector exhibits the world highest sensitivity at room temperature. The GaN-based ...

(PhysOrg.com) -- Overhead transmission lines traverse thousands of kilometers, often crossing remote areas. Inspecting the often ageing lines and the vegetation near them is an important aspect of maintenance, ...

(PhysOrg.com) -- Iowa State University engineers are developing new and improved poles to carry electricity across the countryside. They say the new structures -- which can bend and deflect an extreme load ...

As regulators pave the way for wind-farm development with tax credits and loosened regulations, the key challenge facing developers is that existing transmission lines, substations and transformers are inadequate to handle ...

(PhysOrg.com) -- When it comes to carbon nanotubes, the majority of research so far has focused on small-scale applications. But now, a team of researchers from Rice University has created carbon nanotubes ...
